USB device drivers use to talk to USB devices. This is probably
still a bit rough and it does not yet include the functions specific
to HID, ethernet, hubs, host controller drivers, task threads or
debugging.
with upper and lower case letters from the English alphabet. Change
the number of possible file names mktemp will return from 26**6
to (10+26+26)**6 instead. This keeps things consistent with mkstemp(3)
force allocation of unallocated BARs (cardbus uses this to preallocate
everything). Add a prefetchmask to allow for busses that get prefetch
hints to set them. Addjust pci_add_map and pci_ata_maps to take a new
force flag which pci_add_resources will pass in. Implement 'force' in
pci_add_map. Write new value of allocated resource into the bar, if
the allocation succeeded (we should have done this before, but with
the new force the bug was very obvious).
- The code that creates hints.c and env.c from the skeleton files
moved into separate functions.
- Sanity checks for missing "ident" and "cputype" directives moved
into main(), alongside the existing check for "machine".

- Provide tunable vm.memguard.desc, so one can specify memory type without
changing the code and recompiling the kernel.
- Allow to use memguard for kernel modules by providing sysctl
vm.memguard.desc, which can be changed to short description of memory
type before module is loaded.
- Move as much memguard code as possible to memguard.c.
- Add sysctl node vm.memguard. and move memguard-specific sysctl there.
- Add malloc_desc2type() function for finding memory type based on its
short description (ks_shortdesc field).
- Memory type can be changed (via vm.memguard.desc sysctl) only if it
doesn't exist (will be loaded later) or when no memory is allocated yet.
If there is allocated memory for the given memory type, return EBUSY.
- Implement two ways of memory types comparsion and make safer/slower the
default.
the line continuation backslash doesn't cause "warn" to print "return".
2. Group "warn" and "return" together as the "return 1" should be
performed only if the "kldload nfsclient" also failed (and not
already if the "vfs.nfs" sysctl(8) check failed).

This should reduce huge playback / recording latency for
applications that try to act smarter and manage their own
buffering (XMMS, Skype, etc.).
Note to Skype + via8xxx users: Remove previous hackish
"hint.pcm.<unit>.via_dxs_disabled" from kernel hint and see
whether this changes cure all those annoying sound issues.
but broke handling of the turboG channel; since we aren't ready to revamp
the channel list just check for turboA channels for now so channel 6 is
considered in auto mode

try very hard to be perfect. However, these attempts broke down when
there were large numbers of resources. We'd not be able to map them all.
Instead, accept that we might pass more range to thse subbus than
might be optimal be able to compute. However, there's little harm in
this and it allows us to pass greater resources through.
# it has been suggested that we allocate a fixed amount of resources
# on attach and give it out upon request. This might not be a bad idea...
The race is very real, but conditions needed for triggering it are rather
hard to meet now.
When gjournal will be committed (where it is quite easy to trigger) we need
to fix it.
For now, verify if it is really hard to trigger.
